Final answer:
Endocytosis is the process where cells internalize large particles such as food through active transport, including phagocytosis (cell eating), pinocytosis (cell drinking), and receptor-mediated endocytosis.
Step-by-step explanation:
The type of transport where a cell takes in a large particle, such as food, is known as endocytosis. Endocytosis is an important active transport process by which cells internalize particles including macromolecules, parts of cells, or whole cells. This is different from other processes such as diffusion and osmosis, which involve the movement of small molecules. Phagocytosis, a form of endocytosis, is commonly referred to as "cell eating" and it allows a cell to engulf large particles like food or bacteria, enclosing them in a membrane-bound vesicle within the cell. Similarly, pinocytosis, or "cell drinking," involves the ingestion of fluid and the solutes dissolved in it into small vesicles. Lastly, receptor-mediated endocytosis is a more selective form of endocytosis where specific molecules are taken up after they bind to receptors on the surface of the cell.
